Energy homeostasis is the result of a balance between energy intake and expenditure, and the hypothalamus plays a key role in the regulation of these processes. The hypothalamic prolactin-releasing peptide (PrRP) is involved in food intake regulation and energy homeostasis, although only its lipidized analogs exert central anorexigenic effects after peripheral administration. The aim of the present...
Cholecystokinin (CCK) and leptin are two important satiety factors that are considered to act in synergy to reduce meal size. Peripheral injection of CCK activates neurones in several hypothalamic nuclei, including the supraoptic (SON) and paraventricular (PVN) nuclei and neurones in the brainstem of fed rats. We investigated whether peripheral leptin would modulate the effects of CCK on neuronal...
